I do not understand the purpose of this rule. To my knowledge, there are no tactical spells that could have any effect if used in the 3rd Magic Phase. Does this phase serve a purpose? I don't doubt I could be msising something here! Or is it there for possible future spells in later games that might have an effect in the 3rd Magic Phase? Or is it a leftover from earlier playtest versions, but no longer serves any purpose? What am I missing?
